WASHINGTON – In the days before his firing by President Donald Trump, FBI Director James Comey told U.S. lawmakers he had asked the Justice Department for more resources to pursue the bureau’s investigation into Russia’s interference in last year’s presidential election, three U.S. officials said Wednesday.

The officials said Comey met last week with Rod Rosenstein, the deputy attorney general, to make the request. Comey then alerted lawmakers with ties to the concurrent congressional investigations into Russia’s meddling, according to the officials, who insisted on anonymity in order to disclose the private conversations.

Justice Department spokeswoman Sarah Isgur Flores said it was false that Comey had asked Rosenstein for money for the Russia investigation.

The revelations raise new questions about what prompted Trump’s decision to fire Comey. The White House has cited a memo from Rosenstein, in which he criticizes Comey’s handling of last year’s investigation into Democrat Hillary Clinton’s email practices
